Pressure is defined as the force per unit area exerted on a surface.[1]
English units used for air pressure include:
- atmospheres
- pounds per square inch (PSI)
- inches of mercury, which is the number of inches the given pressure will raise a column of mercury
SI units for pressure are Pascals, where 1 Pa = 1 N • m-2
See also
- blood pressure - typically measured in millimeters of mercury
